Were other recording files there?

No. The only thing that you have to be careful to line up is the host
name--the recordings must exist on the recording host. If you change
host names, you'll need to update the host name in the database using
the restore script (
, but no restore is required).
Most likely your Storage Groups configuration needs fixing to contain
the directory locations at which you've mounted the recording
directories. I'm guessing that this changed.
